    Hi,

    1. Is the radhtmlplaceholder actually drawing the placeholder over Silverlight like we do it with iframe object placed and adjusted over the silverlight page.
    2. Is there any performance degradation for the control.
    3. Is there any issue in alignment it will cause when resolution changes or screen's size is adjusted.
    4. Is there any major issues/bugs found in the control, which are known and have no workaround.

    Please also give me possible technical details or links which refer to this of the control if any.

    Thanks in advance

    Hello veena,

    Up to your questions:
    1. Is the radhtmlplaceholder actually drawing the placeholder over Silverlight like we do it with iframe object placed and adjusted over the silverlight page.

    >> Telerik: We use iframe only when loading external content (url), otherwise we just position a HTML DIV element above the Silverlight application.

    2. Is there any performance degradation for the control.

    >> Telerik: The application that uses this controls should set the Windowless property to On. This is causing some performance penalties in particular scenarios. Read more info here:
    http://blogs.msdn.com/silverlight_sdk/archive/2008/11/12/limitations-of-windowless-mode-for-silverlight.aspx

    3. Is there any issue in alignment it will cause when resolution changes or screen's size is adjusted.
    4. Is there any major issues/bugs found in the control, which are known and have no workaround.
    >> Telerik: Yes - have this issue with bigger DPI (120) in the default DPI we are not aware of any issues. Other limitation is that you can not show anything from the silverlight application above the html placeholder - windows, popups, menus, etc - they will hide beneath it.

    If you face any problems with the control - please let us know.

    1. Is there any issue in alignment it will cause when resolution changes or screen's size is adjusted.
    2. Currently we are facing issue with the zorder of the controls. The RadPane controls must be pinned inorder to make it visible on the side of the htmlplaceholder else it will be placed behind the htmlplaceholder.
    3. What do the external content (url) means in the answer given for Q1.

    Actually our scenario/requirement is something like this:

    1. We want an excel file /pdf file/word file to be visible in silverlight.
    2. Since we could not find any direct approach or control for hosting such files, we thought of converting the excel/pdf/word files to html so that it can be placed in the radhtmlplaceholder.

    Is there any other options for our scenario. Please suggest


    Thanks in advance

    Hi veena,

    1. Is there any issue in alignment it will cause when resolution changes or screen's size is adjusted.
    >> Telerik: We are not aware of such an issue.

    2. Currently we are facing issue with the zorder of the controls. The RadPane controls must be pinned inorder to make it visible on the side of the htmlplaceholder else it will be placed behind the htmlplaceholder.
    >> Telerik: Yes, this is a limitation - the only way to workaround it is to hide the html placeholder when you want to show something above it.

    3. What do the external content (url) means in the answer given for Q1.
    >> Telerik: External content is when a web site url is loaded - e.g. http://telerik.com for example.

    Actually our scenario/requirement is something like this:

    1. We want an excel file /pdf file/word file to be visible in silverlight.
    2. Since we could not find any direct approach or control for hosting such files, we thought of converting the excel/pdf/word files to html so that it can be placed in the radhtmlplaceholder.

    Is there any other options for our scenario. Please suggest.

    >> Telerik: One of the options is the one you decide to go with, I'm not sure how complex the generated html will be. But just save the excel file as an Html file and then point the RadHtmlPlaceholder to render this file by using the SourceUrl property - for example:

    RadHtmlPlaceholder1.SourceUrl = "http://mysite.com/myexceldocumentexported.html";. 

    The other option is to point the HtmlPlaceholder directly to the pdf/excel file that you want to open:
    RadHtmlPlaceholder1.SourceUrl = "http://mysite.com/myFile.pdf"; 

    Please let us know how it goes.

    If we try to open the excel/pdf directly by setting .SourceUrl it is prompting with open/save dialog box and the file is opening in the msoffice application window.

    Can we make the excel file to be opened as part of the application itself using a control? We also want the excel file to be opened as readonly and it must not be saved in client system.

    Thanks in advance

    Hello veena,

    Yes - it will for the Excel documents, however for PDF it should open them inside.

    If you want everything to inline rendered the only option is to export it to html file and render it using the html placeholder silverlight control.

    All the best,
